Indeed, looks strange- never seen like this- question: you said 3 month idle time, any hardware changes or similar which could have caused that?, also did you install the 1.5 patch before you started after the long period or did you restart as you stopped before?
Last one- do you use ATI card (model) and FSAA/ AF enabled? 1 pic shows blurred frame, so try to disable either of above, if ATI - do you you use the fix?
NB patch 1.5 makes changes in HUD / dialogs / fonts but should not cause that, even not the map….
